Ernie and Mike painted a fence together in $a$ hours. It would have taken Ernie $b$ hours to paint the fence by himself. What fraction of the fence did Ernie paint? What fraction of the fence did Mike paint?

The base of a circular fence with radius 10 m is given by $x = 10\cos t, y = 10\sin t$. The height of the fence at position $(x, y)$ is given by the function $h(x, y) = 4 + 0.01(x^2 - y^2),$ so the height varies from 3 m to 5 m. Suppose that 1 L of paint covers 100 m$^2$. Sketch the fence and determine how much paint you will need if you paint both sides of the fence.

In 1902, 44 loaves of bread cost the same amount as 1 loaf of bread in 2006. If a loaf of bread in 2006 costs $1.72 more than in 1902, find the cost of a loaf of bread in 1902.

$$A. 3x^3 B. 128x^{11} C. 768x^{11} D. 768x^{28}$$

The base of a circular fence with radius 10 m is given by x = 10 cos t, y = 10 sin t. The height of the fence at position (x, y) is given by the function

$$h(x, y) = 4 + 0.01(x^2-y^2),$$

so the height varies from 3 m to 5 m. Suppose that 1 L of paint covers 100 m^2. Sketch the fence and determine how much paint you will need if you paint both sides of the fence.
